'Magic Mike' made Matthew McConaughey 'nervous'

While promoting his new film "Magic Mike," Matthew McConaughey opened up to Parade magazine about his experience working on the film, which hits theaters this Friday.

"I was very nervous," admitted the star, who plays Dallas in the movie about an establishment of male strippers. "Before I had to go onstage to dance and in front of everyone live, it's kind of nerve-wracking. And then having to strip down, it's very nerve-wracking."

One person who liked what she saw is now-wife Camila Alves.

"My wife now, [she was] my girlfriend at the time, actually showed up and snuck in quite a few days [on the set] and gave me a thumbs up," said McConaughey about Alves, who he married earlier this month. "She said, 'Go for it, baby.' So she's gonna like it."

Channing Tatum plays the title character. The film, set in Tampa, is reportedly based on his days as a male stripper. Alex Pettyfer, Joe Manganiello and Olivia Munn also star.
